Sofirn IF30 Flashlight review
This Sofirn flashlight is ridiculously bright. Sporting thirteen LED emitters and outputting 12,000 lumens of illumination. A very bright flashlight in a compact size. Combines a flood and spotlight beam without compromise that will surely please many flashaholics.

Oberwerk SE 10x42 Binoculars Review
Просмотров 1,3 тыс.4 месяца назад
The best binoculars I've tested? Touted as an improvement to the now discontinued but highly regarded Nikon SE binoculars. Is it really as good as the Nikon SE? The Oberwerk SE binoculars has very good optics with reduced chromatic aberrations thanks to the use of FK-61 ED lenses. Field flatness is also the best I have seen to date.

    I purchased the Orion 20x80 ED binoculars five years ago. They look VERY similar to the Celestrons and I think the specs are nearly identical. They were $300 (again 5 years ago) I also had to send back my first pair due to poor collimation. The 2nd pair they sent me was good, however and I kept them. It sounds like your expectations based on the price were a little high. These binoculars are still not high end instruments. You could spend one to three thousand dollars on binoculars. While the chromatic aberration is much improved on these ED binos compared to the standard binos, there is still some CA present and that was what I expected.

    With a 90mm refractor I can see the red spot (no color) 2 bands and sometimes the northern and southern band. You could try stacking your video and see the results. I don't see color with my achromatic telescope but if I take a picture color comes thru. Your fast refractor is designed for wide field of views and not planet viewing.

    Im guessing thats moisture or some kind of lacquer. This should be perfect matte black, not reflective at all. Its possible that excessive heat caused by the Sun has caused this. If it hurts optical quality and you know how to take it apart and properly adjust them when putting it back together, you can strip the paint/coating off and repaint/coat with some vantablack for the ultimate contrast boost.

    • @FocusKnob
      @FocusKnob 25 дней назад

      Someone told me Celestron sometimes coat the barrels with oil so any dust that get trap inside is caught in the oil. In my case the Assembler was overzealous with the oil application. Ridiculous that oil would be used like this.

      @FocusKnob 2 месяца назад

      You can use synthetic grease or lithium grease. Very little grease is needed for the shutter blade mechanism. I applied grease and then worked the mechanism until it moved smoothly and then wipe off one time any grease that I see so you can't even see it but there's enough residue remaining to provide lubrication. For the barrels and aperture adjustment ring you can be more liberal with the grease.
